Problems solved by technology
When the number of digits of the DAC is greater than 12, the difficulty of design will increase greatly for every increase of one digit. For example, the corresponding DAC needs to increase the accuracy of one digit, and the applied DAC (usually capacitive) will increase the accuracy of one digit. The capacitance index used Larger stages, large capacitors require larger chip areas, increase power consumption, and require more complex circuit structures, reducing the reliability of the design

Description
technical field [0001] The present application relates to the technical field of basic electronic circuits, and in particular, to an analog-to-digital converter, a chip, an electronic device, and an analog-to-digital conversion method. Background technique [0002] With the continuous improvement of the number of precision bits of ADC (Analog Digital Convertor, analog-to-digital converter), the design of CMP (Comparator, comparator) and DAC (Digital Analog Convertor, digital-to-analog converter) is becoming more and more difficult. When the number of digits of the DAC is greater than 12, the design difficulty is greatly increased for each 1-bit increase. For example, the corresponding DAC needs to increase the accuracy of 1-bit, and the applied DAC (usually capacitive) increases the accuracy of each 1-bit, the capacitance index used As the stage becomes larger, large capacitors require a larger chip area, increase power consumption, and require the use of more complex circui...
